INK-'GRINDER.

SPECIFICATION forming part of Letters Patent No. 313,246, dated March 3, 1885. 7

Application filed October 4, 1884 grinding or rubbing up india-ink to proper liquid consistency for the use of architects, engineers, draftsmen, and others.

The invention consistsin an inkgrinder constructed with a saucer-clamp and a chuck adapted to hold the solid ink cakes or sticks, and to be revolved above the saucer, and having means to feed the ink-cake downward as it wears away by friction on the saucer.

The invention consists, also, in particular constructions ofpartsoftheink-holding chuck, to facilitate holding ink cakes of varying shapes and sizes, and in other details of construction, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part'of this specification, in which similar letters of reference indicate. corresponding parts in all the figures.

Figure 1 is a sectional side elevation of my improved ink-grinder. Fig. 2 is a plan View in section on line 00 .r, Fig. 1, and drawn to a larger scale. Fig. 3 is an enlarged vertical sectional elevation of the ink-holding chuck or head; and Fig. 4 is a sectional plan view of the chuck, taken on the line y 7 Fig. 3, and in larger size.

The letter A indicates the base-plate of the machine, and B a standard, which is fastened to the base by screws or bolts 1), passing through the forked arms lb Z) of the standard; andO is a bent arm,which isshown cast in one piece with the base A, but which may be made separate, and be connected with the base at a by screws or other means. The upper end or part of the arm 0 has a screw or bolt end, 0, fixed to it, which passes through the standard B, and receives a nut, c, to hold the parts together, to constitute a 1ight,strong frame to support the operating parts of the machine.

D is-the horizontally-rotating ink-holding chuck or head,which is journaled at its upper end in a bearing, 0, of the arm 0, and has (No model.)

fixed to it the bevel gear-wheel E, which meshes with a bevel gear-wheel, F, fixed to a shaft, G, which is journaled in a bearing, 9, on the standard B, and has fixed to it the crank H,

by turning which motion may be given to the chuck D. The chuck D has an enlarged lower end or foot, D, which is apertured vertically at I, and in one side wall of the aperture is formed the rounding recess J ,which comes opposite to a like recess, K, formed in the face of the clamp block or gib L, which hasahead, Z, by which it hangs loosely within the aperture I from the upper face of the foot-piece D. Screws M M are threaded through the side wall of the foot-piece D, and bear by their inner ends against the inner face of the clampblock L,to hold the cake or stick N of ink between the block L and the opposite wall of the aperture I. The recesses J K allow round or polygonal sticks of ink to be clamped by them, and the adjoining or opposing facesjj and kk of the foot-piece D and block L are for holding square or rectangular sticks or cakes of ink, hence the chuck D is adapted to hold sticks or blocks of ink of any usual shape or size.

Above theapert-ure Land on the chuck-body, is a threaded lug, 0, into which the screw P is fitted, so as to be turned down on the end of the cake N of ink or onto a wooden block, R, placed between the ink and the foot-platepof the screw. The last piece or remnant of the ink-eake may be glued to the end of a block, R, of suitable shape, so that as the block is forced downward by the screw P all the ink may be ground or rubbed up, thus avoiding waste of the ink. The ink-saucers is held by a clamp consisting of a stationaryjaw, T, cast with or fixed to the base A, and a movable jaw, U, to which one end of a screw, V, is swiveled, said screw being threaded through a bearing or nut at o in the arm 0, and having a suitable head by which to turn it in or out, for clamping the saucer S firmly and directly below the chuck D. I show the saucer S made with an overhanging rim portion having a tongue, 8, which enters grooves in the faces of the clamp-jaws T U; but the saucer may have any suitable shape or size, and the clamp-jaw faces be made to correspond,as will r adily be understood. I prefer to connect the pinion E to the chuck D and the gear- ICO wheelF and handle H to the shaftG by means of screws V, which enter the squared ends of the journals or shafts on which the wheels and handle are fitted, and bear by their heads w on the outer faces of the wheels and handle, (see Fig. 1;) but the gear-wheels and handle may be held to place in any other approved way.

In operating the machine the saucer S,from which the liquid ink is to be dipped by the draftsmans pen,is charged with water or other 1iquid,and clamped by the jaws T U under the chuck D, in which the stick of ink N is held by the block L and screws M, so that the ink N will not shake or tremble in the chuck, but may be forced downward to the saucer S,as it wears away by the friction on the saucer as the chuck D is revolved, by turning the crank H by one hand, the other hand being free to feed the ink downward,as required,by turning the screw P.

It is evident that the solid ink N may be ground and the liquid ink in the saucer be brought to the proper consistency in a very short time, and without soiling the fingers or danger of spattering the liquid ink about on the table or work, thereby not only largely economizing time, but avoiding waste of the ink.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An ink-grinder constructed with a saucer-clamp,achuck adapted to hold the solid inkcake and fitted to revolve above the clamped saucer,and having means to feed theink-cake downward as it wears by friction on the saucer, and means to rotate the chuck, substantially as herein set forth.

foot-piece and clamp-block having opposite rounding recesses J K and flat faces j k, as specified, and a feed-screw, P, substantially as shown and described.

5. In ink-grinders, the clamp-block L, made with an upper flange, l, to suspend the block within the aperture I of the chuck, and a rounded recess, K. and flat faces is k, substantially as shown and described.

6. In ink-grindersthe combination,with the ink-holding chuck D, having a foot-piece, D, apertured at I, and the clamp-block L, screws M, and feed-screw O, of the block It, interposed between the feed-screw and the ink-cake N, substantially as shown and described.

7. In ink-grinders, the saucer-clamp constructed with a fixed jaw,T, a 1novablejaw,U, and a swiveled screw, V, and arranged below the ink-holding chuck D, substantially as shown and described.
